s claims., v(o1. 14e- 182) This invention relates to covers or closures, andv more particularly to readily attachable and detachable closures, for covering food grinderhoppers, extrusion outlets, and the like. Y

Food grinders whether used in meat shops, restaurants, homes, or other places, if left exposed after being used, attract flies, insects, dust, and dirt, thereby creating an unsanitary condition, likely to contaminate the foodleft on the grinder. This is particularly -true of meat grinders,` which ordinarily are not provided with closures to protect the exposed inlet and outlet orifices thereof. Recourse is sometimes had to improvised closures of various kinds, such as cloth, paper, wood blocks, or the like, but such closures obviously are not adapted to satisfactorily cover and protect the grinder orices, as they are not properly fitted to such orifices and thereby allow flies, insects, and dirt to accumulate there.

Therefore an vobject of my invention is to provide quickly and easily attachable and detachable closures, for the intake and outlet orifices of food grinders and the'like.

Other objects are to provide a closure, of the type described, which can be produced at a relatively low cost and may be used on grinder orices of varying sizes, said closures being easily manipulated and adapted to be easily placed and positively retained in closure position over a grinder orifice, for preventing the accumulation of flies, insects, and dirt at such places.

Other and further objects of the invention will appear in the course of the following specification.

In the drawing accompanying this specification and forming a part of this application:

Figure 1 is a side elevational view of a meat grinder,

Figure 2 is a top plan view,

Figure 3 is an enlarged elevational View of the outlet side of the grinder,

Figure 4 is a sectional view taken on the line 4-4 of Figure 3, while Figure 5 is a perspective view of the outlet closure member.

In the drawing, the numeral I I refers generally to a grinder, of a well known type and construction, adapted to grind meat and the like, having an upwardly extending hopper I2, receiving a cooperating spout I3, extending downwardly from a circular tray I4, serving as a receptacle for the meat which is fed into the hopper I2, as will be readily understood. A circular cover I5 having a downwardly extending peripheral flange I6 terplaced over the'tray I4 and is retained there by the 'flange I6, in an obvious manner. Preferably a flat hanger I8, formed integrally with the cover I5 and projecting radially from the side thereof, is provided with an aperture I9, permitting the cover I5 to be hung on a nail or peg when not in use, and serves as a convenient handle therefor.

The hopper I2 is mounted on, and is in communication with, a horizontally extending extrui sion casing 20, housing an extruding worm 2|,

driven at its inner end by a motor 22 and adapted to grind and carry outwardly along in the casing 20 meat fed from the tray I4 into the hopper I2, andforce it outwardly through a sieve 23, positioned at the outlet orice of the casing 20, in accordance with recognized practice. ing rim 24, having an internally threaded portion 25 engaging the front outer end of the casing 2U,

is provided with a vertically disposed portion 2B- serving to releasably retain the sieve 23 and the worm 2I in position, as shown in Figure 4.

An annular manipulating handle 21, spaced from and surrounding the casing 20 near the outer end thereof, and connected to the retainingj rim 24 by means of connecting members 28, provides means for readily manipulating the rim 24 in screw-threadedly attaching it to and detaching it from the front end of the casing 20, and this permits the parts to be cleaned or adjusted whenever such operations are required, as frequently is the case with food grinder parts.

A cover 29 for the extrusion end of the casing 20, as illustrated in Figure 5, comprises a generally flat annular portion 30 having an outwardly projecting central portion 3|, and a rearwardly extending peripheral flange 32. A pair of spaced hangers 33, extending angularly from the flange 32 of the cover 29, are provided at their outer ends with curved portions 34 adapted to be looped around the manipulating handle 21, as shown in Figures 1, 2, and 4, for releasably retaining the cover 29 over the extrusion end of the casing 20. The cover 29 may be made of aluminum or other light material, and if desired, the hangers 33 may be formed integrally with the cover 29 by a stamping operation. The cover hangers 33 may be made of pliable material such as aluminum, tin, steel, or the like, in order that they may be bent by the user to engage the manipulating handle, or other cover supporting member of the particular grinder used. Thus the cover 29 may be used on various types of grinders and the like as the hangers 33 may be readily adjusted for use on grinders and the like having various types and minating in a marginal bead I1 is adapted to be 55 forms of supporting members.

A retain- The hopper cover I5 is placed on the top of the tray I4 with the flanges l 6 engaging the top outer portion of the tray I4, and may be removed by merely lifting it therefrom in an obvious manner. The extrusion end cover 29 is placed in acovering position, by merely hanging the curved portions 34 of the cover hangers 33'around the manipulating handle 21, the angular relation of the hangers 33 serving to securely hold the cover 29 against the. extrusion end of the casing 2U, as shown in 'Figures 1, 2, and 4. Attention is drawn to the fact that ythe position and arrangement of the hangers 33 is such that careful or accurate placing of the cover 29 over the extrusion end is not required, as the hangers 33 serve to draw and center the cover 29 tightly against the outer end of the casing 20. The hangersY 33 may be readily'bent to lit various supporting means andv thus the cover 29 has a wide range of adaptability von various types of devices.

It isnot intended to limit the use ofmy cover to meat grinding machines as it may be success-- fully used on many other machines and devices, Wherel an accurately seating and readily detacheabl'e cover is required. Ity therefore Willl be apparent to those skilled in the art, that the invention herein disclosed may be variously changed, used, or' modiiied,` without `departing from the spirit of the invention, or sacrificing the advantages thereof, and that the embodiment of the invention herein disclosed is illustrative only, and that my invention is not limited thereto.

I claim:

l. A,detachable cover for a food grinderv and the like having a generally horizontally extendf ing'casing provided with a food dispensing orilice ina substantially vertical plane at its outer end, a member extending at least partially around the top of saidcasing inwardly from the outer` end thereof, a cover adapted to close said orifice, and a plurality of spaced hangers extending an-` gularly from ythe plane of said cover toward said member, said hangers having hooks at the outerv end'szthereof and' being positioned and arranged in such manner that the hooked ends of saidl hangers are adapted to be looped over said casing member, whereby said cover is suspended by said hangers and drawn against said orifice by its own Weight.
